Q

what is the weak intrinsic ligament which functions to conduct a blood vessel to the head of the femur?

A

capitis femoris ligament

17
Q

what is the anterior ligament of the knee joint that represents the original distal common tendon of insertion of the quadriceps?

A

ligamentum patella

18
Q

what is the extrinsic ligament that runs from the base of the patella to the tibial tubercle?

A

ligamentum patella

important in maintaining alignment of patella relative to articular surface of the femur

19
Q

what are the extrinsic ligaments that are taut when the joint is fully extended and thus contribute to stability when standing?

A

collateral ligaments

20
Q

what extrinsic ligament is located on the lateral side of the knee joint, superficial and separate from the articulate capsule?

A

lateral (fibular) collateral

21
Q

what extrinsic ligament proximally attaches to the lateral epicondyle of the femur and distally to the head of the fibula?

A

lateral (fibular) collateral

22
Q

the lateral (fibular) collateral functions as a _____ and prevents __________ movement at the joint?

A

functions as a wall
and
prevents lateral movement

23
Q

what is the extrinsic ligament located on the medial side of the joint where it blends with the articular capsule and is attached to the medial meniscus?

A

medial (tibial) collateral

24
Q

what extrinisic ligament attaches proximally to the medial epicondyle of the femur and distally to the medial side of the tibia (below medial condyle)?

A

medial (tibial) collateral

25
the medial (tibial) collateral functions as a _____ and prevents __________ movement at the knee joint.
functions as a wall and prevents medial movement
26
what two extrinsic ligaments are found at the posterior aspect of the knee joint?
oblique and arcuate popliteal
27
the oblique and arcuate popliteal ligaments function as _______ and prevent ______________ of the joint, while _________ the posterior aspect of the knee.
functions as a wall prevents hyperextension stabilzes the posterior knee
28
what are the two very strong ligaments which cross each other like an X in the center of the knee joint?
cruciate ligaments anterior and posterior
29
what is the weaker of the cruciate ligaments and runs from the lateral condyle of the femur to the anterior intercondylar area of the tibia?
anterior cruciate
30
what is the stronger of the cruciate ligaments that runs from the medial condyle of the femur to the posterior intercondylar area of the tibia?
posterior cruciate
31
what ligament prevents anterior displacement of the tibia under the femur and thus functions like a rope?
anterior cruciate
32
what ligament prevents posterior movement of the tibia under the femur and functions like a rope
posterior cruciate ligament
